ANIMAL TRAP.

Application filed May 11 "This invention relates generally to traps,

' and has more particular reference'to'anovel 13 by a bracket vsecured to the 'arm.,; The

animal tr'api;

, The invention has for an o'hj'ect'the p-rovisionof ananimal trap, whichwi-ll acteffijciently and effectively, and 'x'vhich is'not readily likely'to'become broken.

The invention has'for a further object, the provision of'an animal trap, which canbe manufacturedand sold ata reasonable cost; ,fjFor further comprehension of the invention' and of the objects and advantages there of, refer'encewill be had to-the following description and accompanying drawings, and

to the appended claims in Which the various novel features of the invention-aremore par ticularly set forth. l 1

Referring to the accompanying drawing, forming a material part of this disclosure:

Fig.1is a perspective view of a device constructed according to-this invention.

Fig. 2 is'a front "view thereof.

Fig. '3 is 'a fragmentary"enlarged-view, as

seen lookin in the direction. of the arrows 33 of F ig'p2. Fig. 4 is a front view of a modified form of 'springfor the invention device.

The reference numeral-lO-indicates gel-'1; erally an arnrformed at one endwvithl a tongue 11 engagin in a groove 12, formed in a second arm 13. On each side ofth'e tongue, and on each side of the groove, these arms are formed With serrations 14 extende ing from one edge to another edge in a curve, and engaging each other, so that the arms may swing'as though pivoted at these ends.

A- spring 15 substantially U-shaped has its upper ends engaged inthe arms 10 and 13 i normally acting to force the arms together using the serratedends as a pivot. The

lower end of the spring 15, may be attached to a support, indicated,by line 16, to support the device.- An arcuate strip 17 is pivotally attached at one end, as at 18, tothe arm 10,

and the other end is provided with a serrated portion 19, and is slidably held to the arm center of curvature'of this ar'cuate strip coincides with the pointof pivotal connec-j tion of the arms 10 and 13.

i The forward end of aica-tch lever 21 n gages one of the serrations 19, the catch lever lever23, also pivoted intermediate of its 'being pivoted intermediate of its ends to the arm 13, as at 22 and the rearward end is engaged by the forward end o'fia second catch 1927; serial No; 190,426:

ends, at 24=tothe arm ThefrearWard end of the second catch lever'23 is engaged by the forward end ofa "third catch lever,- 2*5 pivoted neari-ts rearward end; as at 26- to'the arm 13'. The forward end of a fourth catch l'ever-QT'engagesthc rearward end of the thirdcatch lever '25, and this fourth catch lever is also pivoted intermediate of=its ends to'thearm13', as at 28; :The rearward end ofthe"fourtlrcatch lever- 27 l'ras a string'29 attached thercto, and this string is drawn tightly across-the. front of the device "and se- 1 curedto the, arm 10. Theed ges of the arms 10 and l3, facing each other areprovided The operation of the 'tlevice consists in pivot; point 28. This'causes' the rearward end of lever 27' torelease"'theforward end of lever 25,-the forward end of 2-5 releases'the' rearward i end of 23, the forward end of 23 releases'therearward endof 21, and the for- \vard-end of 21 moves free from the serrat1ons' 1 9; ;he-spring 15 then swings'the arms: 10 and 1 3together, and the teeth3O enrhedthe-mselves" in the animal, holding the animalagainst j e scapel q p r Themodlficatio'n illustrated in Fig. 4 7 discloses a means for varying the acting force 'ofspring 15 which may be used-instead'of spring 15. One of the arms of the spring 15" has one end of an auxiliary spring31 secured thereto, theother end of the auxiliary spring being attached to arack 32 having it's'teeth on its bottom edge, and passing' through an aperture 33 in the other arm of the spring 15. "The bottom ofthe aperture 33 is serrated to mesh With the teeth of the rack,and a wedge 34 is pivoted to the arm of the spring 15 by a screw 35 adapted to secure ii -wedged position against displacement, the wedge being placeable in position to force theteeth of the ra'clragainst the serrations of the aperture 33 tohold the rack as adjusted, which determines the tension of auxiliary spring 31.

\Vhi-le I illustrated and described the preferred form, construction, and arrangement of the several elements employed, it will be understoodthat the device-is nevertheless, susceptible of considerablemodification therein, and I therefore reserve the right and privilege of" resorting to all such changes as may be fairly embodied within the spirit and see 3c of the invention as claimed.

aving thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

l. A device of the class described, comprising an arm formed at one end with a tongue,a second arm formed at one end with a groove engaged by the tongue, the said arm ends being formed with serrations engaging each other, a spring acting between the arms, normally forcing the arms together, using the serrated ends as a pivot, and means between the arms for normally holding the arms apart.

2. A device of the class described, comprising an arm formed at one end with a tongue, a second arm formed at one end with agroove engaged by the tongue, the said arm ends bein formed with serrations engaging each 0t ier, a spring acting between the arms, normally forcing the arms together, using the serrated ends as a pivot, and means between the arms for normally holding the arms apart, the said means being adjustable to control. the distance at which the arms are held.

3. A device of the class described, comprisingan arm formed at one end with a tongue, at second arm formed at one end "with a groove engaged by the tongue, the said arm ends being fOllTlGllWltll serrations engaging each other, a spring acting between the arms, normally forcing the arms together using the serrated ends as a pivot, and means between the arms for normally holding the arms apart, the said means being adjustable to control the distance at which the arms are held and the said means being releasable upon an animal abutting a certain elen'ient thereof.

4. In a device of the class described, a pair of arms abutting each other at one end and normally urged together by a spring, an arcuate strip pivotally attached to one of the arms, and slidably arranged on the other of the arms, the center oi? curvature of the arcuate strip coinciding with the point of rotation of the arms, serrations on the slidable end of the arcuate strip, a catci lever pivotally supported, having its for ward end engaged on one 01 said serrations, a second pivoted catch lever having its forward end engaging the rearward end or the iii-st catch lever, a third pivoted catch lever having its forward end engaging the rearward end of the second catch lover, a fourth pivoted catch lever having its forward end engaging the rearward end ofthe third catch lever, and a trip strip fastened at one till end to the rearward end of the fourth catch lever. a a y 5. A device of the class described, comprising an arm formed at one end with a tongue, a second arm formed at one end with a groove engaged by the tongue, the said arm ends being formed with serrations engaging each other, an adjustable spring acting between the arms, normally forcing the arms together using the serrated ends as a pivot, and means between the arms for normally holding the arms apart, the said means being adjustable to control the distance at which the arms are held and the i said means being releasable upon an animal abutting a certain element thereof. y In testimony whereof I have afiixed my signature. a
